Hi all. I have a 2007 X3 which is about 2 months old. I have 2500 miles on the car. I am getting 15-16 mpg city, and about 21 mpg/highway.

The dealership says this is normal, that the car never achives its rated gas mileage, but I read about others getting the rated #'s.

I use premium gas.

So the question is then, what should I expect? Will the mileage per gallon increase at a certain point in the car's life?

I did have the truck in for sevice recently, and everything was found to check out ok.

it will increase over time. But not everyone gets the same mileage, it's more like a range.
I get 15 mpg on average, but all city driving and with really cold temperatures here in michigan. I got 23 on highway at 85 miles/hour...
Don't worry it will get better...

After about 8K-10K miles you should really see an improvement. The 2007 is supposed to get around 19/City and 27/Highway I believe. My 2005 3.0 is rated at 16/City and 23/Highway. After a good break-in I'm getting the 16/City but usually get 26 on the highway at 70-75 mph. I wouldn't be surprised if the '07 could reach 30/Highway in the right conditions.

It will get better--if you are in a cold weather area then it will be lower--mostly because the gas is re-formulated for winter and has aditives to prevent freezing--also if your gas has 10 or 15 percent ethanol added mileage will be slightly lower. My 07 on a trip from Buffalo to orlando got as high as 27 (warm and flat FL and GA) to 23.5 in the mountains in rain and cold. On a flat run or 70 miles I adv 28 at 75 MPH--but of course that is not real everyday conditions. I find the mileage good for a 4000 lb AWD vehicle with 260 HP!!

Agree with all the above. Your X3 will get better milage as you log on the miles. I noticed the improvement at around 10K which seems to be the point at which everything is nicely run in. I also changed the oil/filter at 6500 just because I am not leasing and may want to keep the car longer than 3 years. I was just not comfortable with going so long between changes. Be sure your tire pressure is to spec also.

I agree with the oil change---especially on the original oil--you know things are wearing in that first few thousand miles and the filter must be full of it--I am going at 5k.

did my oil change at 4000. figured if the ///M gets changed at 1200, mine should be too. =)
